24 Pentium Dual Cores (25th with my girlfriend) + the C2D T9600. So, yep, all that I'm running for now. No crunching on the i7 for now, which is a shame. I'm going to try and acquire another pretty much silent sub-50w setup to use as a dedicated cruncher (looking at the Zotac Z-Box's). And I'm going to ask again about the Mac Mini's....that's IIRC 13 2.4ghz C2Ds.
